**Use AI analytics narratives to draft an explanation of a verified report, not to invent the reason behind a change. Check the data scope, filters, refresh state, metric definitions and comparison before approving each sentence. Keep observations, hypotheses and decisions visibly separate so a fluent summary does not become unsupported business evidence.**

> **Key takeaways**
>
> - Verify the report state before reviewing the narrative.
> - Distinguish counts, rates, percentage changes and percentage points.
> - Treat explanations as hypotheses unless the design supports causation.
> - Record the approved narrative with the exact report scope and date.

## What job should an AI reporting narrative perform?

A useful narrative helps a reader understand the important observations, limitations and next decisions in a report. It should not replace the report's definitions or create certainty the underlying analysis does not contain. Drafting prose is different from establishing the truth of the analysis.

Write the reporting question first. A weekly operations update may ask whether a workflow is healthy. A campaign review may ask whether accepted requests changed. A budget decision may need stronger evidence about incremental impact. Do not let the same generic summary stand in for all three.

Define the audience's decision and the level of detail needed. A senior reader may need a concise exception and proposed action, while an analyst needs the calculation and exclusions. Concision should remove repetition, not the qualification that keeps a claim accurate.

Keep a source of record for metrics. The AI-generated paragraph is a derived artefact, not a new authoritative dataset. If the narrative disagrees with the approved table, investigate the discrepancy rather than choosing whichever version is more persuasive.

## What current Power BI behaviour matters?

Microsoft's checked Copilot narrative documentation describes a narrative visual based on selected report visuals and canvas context. It is not a universal query of every detail in the underlying semantic model. The report design and selected visuals influence what the narrative can use.

The documented narrative needs refreshing after relevant filter, slicer or data changes; it should not be assumed to update automatically with every interaction. A correct summary can become stale when the visible report state changes. Review the narrative after establishing the exact state you intend to communicate.

Footnotes can refer to report visuals. That helps trace an observation, but a footnote is not proof of a causal explanation. Open the referenced visual and check whether it supports the sentence, including the metric, period and filter context.

Current access depends on administrative enablement, supported region and eligible paid dedicated Fabric capacity and workspace conditions. Trial capacity is not the same as supported production access. Confirm the actual environment rather than treating a Power BI licence alone as universal eligibility.

## How do you establish the report state?

Record the data refresh time, included period, filters, slicers, comparison window and relevant exclusions. Identify whether the report is preliminary or closed. A partial current month should not be compared with a complete previous month without an appropriate method and clear label.

Check definitions across visuals. One card may count submitted forms while another counts accepted requests. A chart may use event date while a CRM table uses qualification date. A narrative that combines them can imply a coherent funnel that the report does not actually establish.

| Report-state item | Question to resolve |
|---|---|
| Data refresh | Which source version is represented? |
| Date range | Are both periods complete and comparable? |
| Filters | Which populations and channels are included? |
| Metric definition | What exactly is counted or divided? |
| Attribution | Which system and rules assign credit? |
| Exclusions | What is missing, delayed or deliberately removed? |

Keep the report state with the approved narrative. A screenshot alone may not reveal hidden filters or delayed data. Another reviewer should be able to reproduce the relevant view or understand why it cannot be reproduced exactly.

## How should you review numerical language?

Check each number against the approved table. Verify the unit, sign, denominator and rounding. "Up by five" can mean five requests, five percent or five percentage points. Require wording that makes the intended comparison unambiguous.

Separate volume from efficiency. More requests can coincide with a lower request rate if sessions grow faster. Lower cost per recorded conversion can coexist with lower request quality. A narrative should not collapse several dimensions into a single claim that performance improved.

Review totals and averages carefully. A change in channel mix can alter the overall rate even when each channel's rate is stable. An unweighted average can answer a different question from a combined population rate. Use the [spreadsheet verification lesson](https://mentionx.ai/learn/ai-tools/ai-tools-spreadsheet-analysis-checks) to reconcile the underlying calculation.

Avoid false precision. Rounding should reflect the decision and data quality, not the number of decimals a tool returns. If tracking is incomplete or the sample is small, extra decimal places do not create stronger evidence.

## How do you separate observation, hypothesis and action?

Use explicit labels. An observation describes the reconciled data. A hypothesis offers a possible explanation. An action proposes what to do next. Each can be useful, but they should not be written as though they have the same evidentiary status.

A before-and-after change does not by itself prove that a campaign caused the result. Seasonality, audience mix, tracking changes, sales follow-up and other activity may contribute. An AI summary can list plausible explanations, but plausibility is not confirmation.

If causal inference matters, design an appropriate experiment or analysis with a competent owner. Do not add a universal sample threshold or confidence rule to make a weak design sound rigorous. The evidence standard depends on the question, variability, design and consequences.

Make recommendations conditional where necessary. "Inspect the request-quality decline before expanding spend" can be a defensible operational action even when the cause is unknown. "Double spend because the campaign proved its value" requires evidence the descriptive report may not provide.

## How should narrative revision and release work?

Review the generated body against the actual tool's editing behaviour. The checked Power BI guidance does not treat the generated narrative body as freely editable in place; revision can involve prompting again or moving material into an appropriate alternative visual. Confirm the current workflow rather than promising arbitrary direct editing.

Keep a sentence-level review for consequential claims. Mark supported observation, unsupported inference, stale context or unclear wording. Correct the source report if needed before regenerating the narrative; repeatedly rewriting prose cannot repair inconsistent definitions.

Do not put sensitive instructions or personal information into prompts unnecessarily. Report metadata and interactions can have their own storage and governance implications. Use approved organisational practices and keep the prompt focused on the reporting task.

Approve the final narrative with the report revision and intended audience. A sentence suitable for an internal exploratory review may not be suitable for a public customer claim. Reuse should trigger a check of evidence, permissions and context.

> **Pro move:** Ask the reviewer to underline every word that implies explanation, such as "because", "driven by" or "proved". Each one should have evidence beyond a descriptive change or be rewritten as a hypothesis.

## Worked example: Ledgerline

Ledgerline's illustrative report compares two complete periods. The earlier period has 100 sessions and 10 accepted requests. The later period has 200 sessions and 15 accepted requests. These are synthetic teaching values, not actual performance data.

A generated draft says, "Conversion improved by 50%, proving the new campaign is more effective." The team checks the components:

| Statement | Illustrative calculation or evidence | Decision |
|---|---|---|
| Accepted requests increased | 10 to 15, a 50% count increase | Supported observation |
| Request rate improved | 10% to 7.5% | Incorrect; rate declined |
| Rate change | Down 2.5 percentage points | Supported descriptive comparison |
| Campaign caused the change | No causal design supplied | Unsupported |
| Next action | Inspect mix and request quality | Conditional operational recommendation |

The corrected narrative states that request volume increased while the recorded rate declined, and that the report does not establish the cause. It recommends investigation rather than claiming victory or failure from one metric.

### Walkthrough

1. The analyst confirms complete periods, the accepted-request definition and the report filters.
2. The operator selects the intended report context and refreshes the narrative after establishing that state.
3. A reviewer checks each sentence against the relevant visual and independently recomputes the rate comparison.
4. Unsupported causal language is removed or labelled as a hypothesis requiring further evidence.
5. The owner approves a bounded next action and records unresolved tracking or quality questions.
6. The final narrative is stored with the report revision, scope and data date so later reuse can be checked.

The correction does not make the report less useful. It makes the decision more precise: the team now knows which question to investigate rather than acting on an invented explanation.

## Common mistakes

- **Assuming the narrative sees all underlying data.** Check the selected visuals and context.
- **Changing filters without refreshing the summary.** A previously correct narrative can become stale.
- **Confusing count growth with rate improvement.** Inspect numerator and denominator.
- **Treating footnotes as causal proof.** A referenced chart may support only an observation.
- **Rewriting around broken definitions.** Repair the source report first.
- **Reusing internal exploratory language publicly.** Approval depends on evidence and audience.

## Try it yourself

Take one approved report and record its data date, period, filters, definitions and exclusions. Draft or inspect a short AI narrative. Mark every sentence as observation, hypothesis or action and trace consequential numbers to the source.

Introduce one deliberate trap in a synthetic version: growing volume with a declining rate, an incomplete comparison period or a changed filter without a refreshed narrative. Ask a colleague to identify the defect and explain the correct interpretation.

Deliver a corrected summary, sentence-level review and report-state record. For broader measurement design, link the work to the existing [GEO experiment-design lesson](https://mentionx.ai/learn/measurement/geo-experiment-design-testing-changes) without claiming that an AI narrative itself establishes experimental validity.

## Quick quiz

**1. Does the checked Power BI narrative automatically represent every detail in the semantic model?**

*Answer:* No. Its scope depends on selected report visuals and canvas context.

**2. Can request volume increase while request rate declines?**

*Answer:* Yes. The denominator can grow faster than the numerator, as in the illustrative example.

**3. What should happen after relevant report filters change?**

*Answer:* Refresh and recheck the narrative rather than assuming it remains current automatically.

## What should you check before moving on?

Confirm the narrative matches the exact report state, uses correct numerical language and separates explanation from observation.
